Question

The sales of a book publication  are expected to grow according to the function S=300000(1-e^-0.06t) where g is the time , given in days  showing using differentiation that the sales never attains an exact maximum value.

What is the limiting value approach  by the sales function?

 

A poll commissioned by a politician  estimates that t after he makes a statement,  denegrating women, the percentage of his constituency( those who support him at the time he made the statement)  that still supports him is given by S(t)=75(t^2-3t+25)/t^2+3t+25

The election is 10 days after he made the statement if derivatives  S'(t) may be thought of as an approval rate, derivate the function for his approval rate.  

When was his support at its lowest?

What was his minimum support level?

Was the approvals rate positive or negative  on the date of the election
